| | -ne operator Hi I have a script that accepts an argument from the user. There are four possible values that I wish the user to pass to the script. I wil then take different actions based on the argument passed. If I do not get one of those values I want to error out. I am not really sure how to use the the operators. What I have so far $Input = $args[0] If ($Input -ne "1") { Write-Host "Error" Break } So here I will break out if I do not get 1 as an input. I also want to error out if I don't get 2, 3 or 4. I have tried: If ($Input -ne "1" -ne "2" -ne "3" -ne "4") { Write-Host "Error" Break } but that doesn't work.. Anyone have any tips? Thanks Simon |
